aticonfig syntax/input data?

[trentzb]

If your card(s) are supported then the following will set your mem clocks to 300 for adapter 0:

Code:

glakkeclock -oscm 300 -ostcs -cdi 0

Remember you have to issue this command while the card is under full load (PP mode 2 I believe) else you will be adjusting the values for the idle mode or whatever mode the card is currently operating in. Alternately you can specify the PP mode to apply values to (-cpl I believe) but I have never tried that so I am not sure.

ahh, I haven't seen that Generic Error before. Try using the command I listed and see what happens. And try just doing mem itself and the core itself before doing both in one call.

No dice.  Same behavior.  All glakkeclock does is seem to reset the lower end for peaks not actual clocks.  Even if I use aticonfig to then subsequently reset the clocks to somewhere in the new lowered range, it only does the peak.  The effective clock remains the same.

I've tried under 0 load and full load.  Same behavior.

./glakkeclock -oscm 300 -oscg 600 -ostcs -cdi 0

Default Adapter - AMD Radeon HD 6900 Series
                            Core (MHz)    Memory (MHz)
           Current Clocks :    600           1250
             Current Peak :    600           300
  Configurable Peak Range : [600-840]     [300-1325]
                 GPU load :    99%

                  Sensor 0: Temperature - 72.50 C
Fan speed query:

Then:

aticonfig --odsc=700,300


Gives:

                            Core (MHz)    Memory (MHz)

             Current Peak :    700           300

So, it seems as though glakkeclock works for core clocks and peaks, but not for memory clocks.  

It only seems to reset memory "peak" which from what I can tell does nothing.  My chip runs at the same temp and mH/s.  Similarly, the memory clock remains unchanged.

EDIT:  If I try to set my memory clocks somewhere ABOVE the factory default minimum of 1250, that still does work.  So there seems to be something in the card (?) that is only allowing glakkeclock to mess with core settings, not memory.

EDIT2:  Tried backing down clocks more slowly.  Guess what, glakkeclock WILL let me set memory to as low as 700, but that's it.  Anything below 700 and it's the same behavior as above.

Sadly, that doesn't give me much help in terms of temp and/or speed.  My chips are already running close to max core (835/840) at 75C.  Changing the memory clock to 700 does save me a few deg C (down to 72.5) but no love in terms of speed.  ;-(

That seems odd. I can't confirm or deny as I don't have 69xx cards.

Just for kicks, try the following (after reboot/reset and running full load) and report what you find:

Code:

./glakkeclock -ogcm -ogpl -cdi 0
./glakkeclock -oscm 400 -ostcs -cdi 0
./glakkeclock -ogcm -cdi 0
./glakkeclock -hgil -cdi 0

Also, Andre has been extremely helpful with resolving issues with glakkeclock. I believe his email is in the header of source code. I contacted him some months ago with issues and we worked together via IRC to resolve issues and clean up some code.

Oh well, not a big deal.  The cards are running 95% and above factory core peak.  Worst case I'm burning some watts on the higher memory clock.

Did you mention that aticonfig also doesn't allow you to set mem clock to where you need it? I don't recall if you mentioned this or not.
